# `embedMany()`

Embed several values using an embedding model. The type of the value is defined
by the embedding model.

`embedMany` automatically splits large requests into smaller chunks if the model
has a limit on how many embeddings can be generated in a single call.

```ts
import { embedMany } from 'ai';

const { embeddings } = await embedMany({
  model: 'openai/text-embedding-3-small',
  values: [
    'sunny day at the beach',
    'rainy afternoon in the city',
    'snowy night in the mountains',
  ],
});
```
